I have an Apple keyboard -- it's very possibly the nicest keyboard I've ever used. HOWEVER, it doesn't have an [Insert] key, which, needless to say, is extremely frustrating. I can work around this in the pattern editor itself by changing the keys, but in the sequence editor, I can't seem to alter the default keymappings.

Am I missing something, or is this functionality missing? If it is missing, could it please be added?
